Many of these domains benefit from processing the data as close to the source as possible, e.g. in Internet of Things applications we see a paradigm shift towards Edge processing, and in the Web, we see more and more effort towards decentralization of the Web where applications run directly inside the browser. However, current Stream Reasoning engines are not able to reuse the same code-base to run applications in the cloud, edge, or browser. In this paper, we present RoXi, a Reactive Reasoning framework that provides the needed building blocks to realize Stream Reasoning applications that can target cloud, edge, and browser environments.engProceedings paper10.1007/978-3-031-43458-7_30WOS:001560618200030
